TPS536C9T: PMBus details for TPS536C9T

Part Number: TPS536C9T
Other Parts Discussed in Thread: TPS53679

Tool/software:

I am looking for PMBus details for TPS536C9T. The datasheet does not discuss the PMBus interface. Where can I find PMBus Command map with detailed inputs/outputs (manufacturer ID, Read protocol, write protocol, etc).

We have a Linux kernel drvier for tps53679  (https://kernel.googlesource.com/pub/scm/linux/kernel/git/zohar/linux-integrity/+/refs/tags/integrity-v5.14/drivers/hwmon/pmbus/tps53679.c). Is this part compatible with tps53679 or can you highlight what is different?

    Hi Terry,

    Please reach out to vr@list.ti.com for the full Technical Reference Manual which will have the full PMBus commands. 

    The major difference for TPS536C9T is that TPS536C9T uses the ULINEAR16 number format, while our other parts such as TPS53679 have used VID format.

    Regards,

    Maha
